Guidance to solve exercise 4 on page 68 SGK mathematics 4
Problem Statement:
A rectangular stadium has a length of 180m, and the width is half of the length. Calculate the perimeter and area of the stadium.
Solution Method:
- Calculate the width of the stadium by dividing the length by 2 (because the width is half of the length)
- Calculate the perimeter of the stadium by applying the formula for the perimeter of a rectangle: Length plus width, then multiply by 2
- Calculate the area of the stadium by applying the formula for the area of a rectangle: Length times width.
Answer:
The width of the stadium is:
180 : 2 = 90(m)
The perimeter of the stadium is:
(180 + 90) x 2 = 540 (m)
The area of the stadium is:
180 x 90 = 16200 (m2)
Final result: Perimeter: 540m ;
Area: 16200m2
